In the closely contested Connecticut's 1st congressional district Democratic primary set for August 11, trader consensus slightly favors former Hartford Mayor Luke Bronin at 47% over incumbent Rep. John Larson at 38.5%, driven by Bronin's fundraising dominance—$1.8 million cash on hand versus Larson's $1.1 million as of Q1 2026—and his April 24 endorsements from Hartford's mayor, city council members, and local Democrats emphasizing generational change. Larson's tenure since 1999, March internal poll lead, and May 1 Working Families Party backing, which criticized Bronin's labor record, keep the race tight. Absent independent polls, further endorsements, party convention outcomes, or turnout shifts among younger voters could create separation, with lower-tier candidates like Jillian Gilchrest trailing.
